Vinventionrelates toiagitating and lmix lng apparatus for materials ofany' lindgalT though it hasbeen especially designed for concrete aggregates. The invention particu-V 5 Nlarly hasfor itsobject to provide'certain nevir s truinentalities,V all arranged as a' unit that may be placed v-in anydumptruck body'with outalteration of theftruck body.

Further, the invention hasfor 'an object to provide ineansfwher'eby the aggregatewill not pack in corners of the'receptaclebut all material will be thoroughlyand uniformly mixed `togetlierby the action off the agitators,

Further, the invention has for it's'object toV provide a mixing and agitating apparatus in which a row of agitatorsY is moved bodily as a unit back and forth `from frontendto back end of the receptacle (somewhat as ai comb), `each agitator being rotatedf onf-its axisas the movement back'and forth occurs.`

Further, it is anobjectlto provide a rovi/' l fof e 30 (preferably rotatable),l agitators arrangedjas a comb landmoved back-and forthffroin end. to end of the receptacle', the rovv.being'slfiiift` edl transversely of the receptacle as it rea'cles the front and back limits of its Atravel so thaty theagitators travel in straight parallel' lines of twiceV the number as there are agitator-s.

A driving Vbevelled pinion 16 lmeshes with abevelled gear 17 on a driven shaft 18 that is journalled in suitable bearings 19 on the platform or bed 15,v and the- 24. A cross chain 25 passes over the upper` sprockets 20-20 so that both sprockets may be driven Vby the power plant.

yMounted beneath the Y hannel iron 26 and bearing 27 are stub shafts 28 which carry sprockets v29, around which sprockets 29 and around' the respective'sprocketsf21 and 24 the two longitudinal chains 30 pass. Each of the chains 30carries a pin socket 31Y hereinafter again referred to. 32 and 33designate the outer-and inner side plates of the trolleys, which plates are spaced apart by sleeves 34 and connected by connecting bolts 35. Each plate also carries a pair ofl trolleyl wheels36 mounted on studs 37 .while the outer plates 32 carry bumpers 38 forra purpose presently explained.

Connecting the two trolleys are transverse bars 39 spaced apart and having angled ends 40 vsecured to the outer plates 32V of the trolleys by bolts orcap screws 41. 42 is a sliding barv that is mounted between the bars 39 andis supported by rollers 44 on upper andY lower carrying vbars 43 that are secured to the sliding bar` 42 at itsV endsy asbestl shown in Figure 10 of the drawings.

.A The sliding barY 42 carries a set of shaft bearings 45 for the agitator shafts 46, on which the longitudinal agitators 47 are secured in-'any suitable way, the agitators havingany desired number of fingers 48, four being shown for convenience of illustration. Each agitator shaft carries a sprocket 49 andan endless drivechain 50 passes around allofthesejsprockets. drivingsprocket 51 is also mounted on thejcentral agitator shaft to engage a xed chain 53 on the periphery or marginal edge of the channel viron 52 which is mounted .Y beneath the cross .bars of the frame as a partof'the frame, the channel iron 52 having its front and rear ends rounded as shown. The fixed chain 52 serves as a rack` member and the sprocket 51 as a pinion member, the purpose of which will presently appear.

There are two guide blockis- 5,4 secured tothe slide bar toengagethe channel iron 52 on the side opposite where the sprocket 51 engages the fixed chain 53 so as tohold the sprocket continuously in meshwithY the chain whilethe agitator caris moving lengthwise of the receptacle orbody. Y v

are provided to cooper- .Idler sprockets .55

The motor 11 and ate with the chain 50 to maintain it in constant mesh with the sprocket 49 of the central agitator. Y Y

56 designates supports for the guard and baflie plates 57, which guard and baliie plates 57 are placed over the frame to prevent the material being filled into the body from collecting on the driving chain, etc.

58 represents the dump truck body and 59 designates pins on the chain 30 which fit the sockets 31. Y j

Assume the parts to be positioned as indicated in Figure 1 and power being applied to move the trolley car rearwardly. As this motion takes place the left hand agitator will lieclose to the left hand side of the body 1 while the right hand agitator will be spaced away from the right hand side of the body 1, all three agitators moving rearwardly as a unit by virtue of the pin 59 and socket 31connection between the chainsA 30 andthe `slide bar 42. As the drive sprocket or pinion memberis in mesh with the fixed chain or rack member 53, rotation is imparted to all of the agitators; Now, as the trolley car reaches the rear end of the frame the pin and socket connections 'will pass Varound the sprockets 29 and begin to return the car to the forward position. At the same time that the pin and socket connections 594-31 pass around the lsprockets 39 the `driving sprocket or pinion member 51'will pass around the rear end yofthe channel iron 52 and in'doing so move the slide bar 42 fromleft to right,

thereby 'bringing the right handv agitator adjacent the right hand wall of the body 1 and the left hand agitator away from the left hand wall of the body 1 as well as moving the central agitator from the left side tothe right side of thechannel iron 52.

Becauseof the rounded ends 2 of the body 1 lthe agitators, while the Vtrolley car is at the end of the frame, will turn in the same proximity to the corners vas they do to the side material forming lat the corners of the body.

Inorder to reduce shock the bumpers 38Y cation, directly on` the chassis of a dump truck.

By the vconstructionl illustrated and described I accomplish with three agitatorl fingers or tines what wouldrequire six to accomplish were the mechanism like that' of a.'

my prior application.

Further,.by giving a rotary motion to the agitators, as well as a rectilinear motion, a more complete mixing and agitating ,of the material within vthe receptaclebody '1V is V0bwalls of the body 1, thereby preventing dead` tainable thanwith apparatus of the prior art` Vwith which I am familiar Y i From the foregoing description, taken in l.
